Model BND-LD Tracking Index Test Apparatus for measuring the electrical breakdown properties

Model BND-LD Tracking Index Test  Apparatus 

Introdution:Tracking Index Text Apparatus BND-LD creates moist conditions by providing drops between electrodes to measure the electrical breakdown(tracking) properties of an insulating material .

Standard:IEC60112  ,IEC60745, IEC60335-1, IEC60598-1.

Application: It is widely used for electrical safety assessment of electrical apparatus.This machine mainly tests the resistance tacking permance of  solid insulating materials,which may be exposed to moisture and dirty environment.

Features:automation control systems;digital display.

Instruction:                                                                                                                                                            

The Tracking Tester is a fully automatic instrument contained in its own cabinet to maximize the safety of the operator. Inside the well lit cabinet, a test specimen is placed on a glass plate and two platinum electrodes are lowered onto the top surface. A gauge block is supplied with the instrument to ensure the electrodes have the proper distance between them. The table height is easily adjustable to ensure the proper angle of the electrodes and height of drops. The rest of the test is controlled from outside the test chamber with the door closed. The voltage, limiting current, drip rate and number of drips are all set on the control panel. An operator should observe the test to see if a flame ignites. The instrument sounds an alarm if there is a tracking failure of at least two seconds.
